Check Digit Verification of cas no
The CAS Registry Mumber 914922-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,4,9,2 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 914922-89:
(8*9)+(7*1)+(6*4)+(5*9)+(4*2)+(3*2)+(2*8)+(1*9)=187
187 % 10 = 7
So 914922-89-7 is a valid CAS Registry Number.
